I’ve seen that insufficient humidity levels can cause a lot of problems.
The ideal relative humidity for optimum health and comfort is somewhere between 30 and 50%.
Air that’s too dry can cause damage to home furnishings. The dry air pulls moisture out of hardwood floors, moldings and antiques, sometimes resulting in the wood cracking. Anything that’s made from wood will begin to warp, shrink and bend. Wood floors may end up creaking and separating. It can make skin feel cold and itchy and aggravate symptoms of asthma and allergy. Chapped lips, bloody noses and headaches can often be blamed on a lack of proper moisture levels. Overly dry air can dry out mucous membranes and increase the risk of respiratory infections and sore throat. Maintaining proper moisture levels is vital to feeling good. Humidity can even affect sleep patterns. After dealing with all these problems for several years, I finally did some research. I learned that a whole-house humidifier is a worthwhile investment. It is installed into the air handler of the heating system and automatically introduces necessary moisture into the heated air. The result is a more comfortable home at lower thermostat settings. Lowering the temperature has reduced demands on the furnace and saved quite a bit of money on monthly heating bills. I assume less wear and tear on the equipment will minimize the chance of malfunction and lengthen the lifespan of the furnace. Plus, my family has had less complaints with health issues, and I feel we all have more energy during the day.
